If you are trying to get python, perl or cgi scripts to work with Apache and you come across this error.
[Thu Sep 25 09:36:28 2014] [error] [client x.x.x.x] suexec policy violation: see suexec log for more details
[Thu Sep 25 09:36:28 2014] [error] [client x.x.x.x] Premature end of script headers: x.py
you can fix this either by configuring suexec properly(which require efforts beyond this discussion) or by disabling suexec.
Disable suexec in apache(centOS)
1. Run command (to get suexec location):
httpd -V | grep -i suexec
-D SUEXEC_BIN=”/usr/sbin/suexec”
2.Move suexec binary:
mv /usr/sbin/suexec /usr/sbin/suexec.unused
3.Restart apache:
service httpd restart
